The small print on Chase freedom CREDIT CARD?

So i want to apply for the CFCC. My main reason it offers a 12 month 0% apr. I currently have a chase master card and i had a full 12 months of 0 apr and it was smooth and great. So before apply for this new CFCC i read the fine print and next to the intro apr it stated…(THE INTRO 0 PERCENT APR WILL BE 12 BILLING CYCLES OR 6 MONTHS BILLING CYCLES DEPENDING ON CREDIT HISTORY) ahaaa….well my question is what are the determine factors of this card being either 12 or 6 months of 0 percent apr?
what specific type of things will be the determing factor

Based on what you have written the answer to your ? is this:
The determining factor in in whether you the 0% rate will be 6 months or 12 months is your credit history.
